The vehicle is a 2010 FX4. I currently have a HBS 2" leveling kit installed and want to put a 2.5 inch block in the back (the AS 3 inch will be to much rear lift). I found some pro comp blocks online but im not sure which one I need. They have different pin sizes ranging from 9/16, 5/8, and 3/4. Here is a link to the ones that I found: http://www.4wheelparts.com/Lift-Kits...8in.%29_PQ=2.5. So which one do I need?

 

anyone?? Im sure someone on here has one of the Pro Comp kits.

 

If no one answers you, later today I will measure the size on the ones I removed and post the size for you......

 

why will the 3" blocks be too much? i have them on my truck with the 2" front and it sits level.

 

First off, your truck looks fantastic!! Im assuming you have the AS 2" kit which actually gives you closer to 2.5 inches of lift. My HBS kit actually raised my truck 2 inches. I have seen pics of people trucks with the AS 1.5 kit which actually raised it about 2 inches and there was a little to much rake for my liking. What rims and tire combo are you running?

My 2010 XLT, 4x4 has 3/4 inch pins. One male and one female in the center of each cast iron block. My 2004 truck may of had smaller ones??

 

thank ya

 

Where are you guys getting your autospring blocks from?

Can anyone confirm they are 3/4 inch?

 

dont mean to hijack, but would an add-a-leaf be better then a rear block if I was going to haul my ATV in the back. I sit level now,(bilstein 5100s) but when I put my sportsman 500 in it, i am nose high.

 

yes, i'm getting ready to buy an add-a-leaf too.. a block will lift it up, but add a leaf will give you... ANOTHER leaf for a little added strength agains sagging and lift you up a little bit.

 

let me know where you get yours from

 

I really like your truck. Looks amazing. How does it ride compared to stock? I didnt check your sig but did you have to change your shocks? Also any noticeable loss in fuel mileage or performance?
